Abstract
With an object of realizing an intruded object capable of carrying out magnetic resonance imaging in a state of being intruded into an object and a magnetic resonance imaging apparatus for capturing an image of the object having the intruded object, at least a unit of an intruded object 400 such as a piercing needle intruded into an inner unit of the object, is constituted by a substance 402 or 404 having an atomic nucleus having a gyromagnetic ratio different from a gyromagnetic ratio of spin of an atomic nucleus of a substance occupying a majority in the object.
Claims24
An intruded object which is a body intruded into an inner unit of an object for executing magnetic resonance imaging, wherein a unit of the body comprises a substance having an atomic nucleus having a gyromagnetic ratio different from a gyromagnetic ratio of spin of anatomic nucleus of a substance occupying a majority in the object.
A magnetic resonance imaging apparatus comprising:
- a signal acquiring device for acquiring magnetic resonance signals respectively of an object for executing magnetic resonance imaging and a body which is intruded into an inner unit of the object and at least a unit of which comprises a substance having an atomic nucleus having a gyromagnetic ratio different from a gyromagnetic ratio of spin of an atomic nucleus of a substance occupying a majority in the object;
- and
- an image forming device for forming respectively an image of the object and an image of the intruded object based on the magnetic resonance signals.
A magnetic resonance imaging method comprising the steps of:
- acquiring magnetic resonance signals respectively of an object for executing magnetic resonance imaging and a body which is intruded into an inner unit of the object and at least a unit of which comprises a substance having an atomic nucleus having a gyromagnetic ratio different from a gyromagnetic ratio of spin of an atomic nucleus of a substance occupying a majority in the object;
